The federal immigration agent who repeatedly shot Marimar Martinez one year ago fired his final shot into the rear passenger window of her fleeing vehicle as she crouched against her steering wheel, her attorneys revealed Monday while announcing a lawsuit.The detail comes from a forensic reconstruct ion her attorneys are using to support Martinez’s highly anticipated lawsuit against the federal government. She plans to sue over her Oct. 4, 2025, shooting by Border Patrol agent Charles Exum in Brighton Park — and the failed prosecution that followed.Martinez had yet to file her lawsuit early Monday afternoon, when she joined her attorneys for a downtown news conference to discuss the reconstruction and impending litigation. Related Marimar Martinez, shot by Border Patrol in Chicago, speaks out after Good, Pretti deaths: ‘I am their voice’ Still, it’s another step in the broader push for accountability one year after Operation Midway Blitz. The Trump administration deportation campaign that hit Chicago last fall has prompted several lawsuits and a bid for criminal charges against agents like the one who shot Martinez.So far, no Midway Blitz agent has faced criminal charges for on-duty conduct.The Chicago Police Department has begun to investigate Martinez’s shooting, though. And the probe has been assigned to a unit staffed with deeply experienced detectives who will look to bring a case to Cook County prosecutors, the Chicago Sun-Times has reported.Now, Martinez and her lawyers are moving forward with their own efforts. Their reconstruction of the shooting scene further undermines the feds’ original claim that Martinez and another man “rammed” agents with their vehicles, and that Martinez drove her vehicle toward Exum.Martinez’s lawyers said the analysis shows Exum fired three shots into the windshield of Martinez’s Nissan Rogue, another into the front passenger side and a fifth through the rear passenger side.At Monday's news conference, lawyer Michael Gallagher said his team's experts have “objective proof that this was a bad shoot. That everything Exum said was a lie. And most importantly, Marimar is telling the truth.”Christopher Parente, another lawyer for Martinez, insisted that his client's shooting isn't a political issue.“We are asking the Department of Justice to do something," he told reporters. "It’s not the Department of Republicans. It’s not the Department of Democrats.”Martinez, a U.S. citizen born and raised in Chicago, suffered seven wounds but survived. She began to prominently criticize the Trump administration’s deportation campaign early this year, after immigration authorities in Minneapolis fatally shot Renee Good and Alex Pretti.“I am their voice,” Martinez told the Sun-Times. “I am here for a reason.” Marimar Martinez, who survived being shot five times by a federal immigration agent in October 2025, shows one of her bullet wounds during an Illinois Accountability Commission hearing at the Bilandic Building on April 28.Sun-Times Homeland Security officials quickly labeled Martinez a “domestic terrorist” after her run-in with Exum. Chicago U.S. Attorney Andrew Boutros’ office also brought charges against her for assaulting a federal agent — only to drop those charges 46 days later.Still, Martinez’s lawyers say a trove of evidence from that prosecution shows Exum lied to justify shooting Martinez. "Who’s the real domestic terrorist?” Parente said at the news conference, after presenting some of the evidence. The Illinois Accountability Commission concluded in April that Exum “shot an unarmed civilian without apparent justification”; that “evidence was deliberately tampered with and destroyed”; and “federal agents produced materially inaccurate official reports.”Martinez did have a firearm with her that day, but it was inside a snapped-closed bright-pink holster at the bottom of her purse, court records show.Gov. JB Pritzker, who established the commission, wrote on social media this weekend that Martinez “deserves true justice and accountability from the federal government.”Martinez’s shooting was also cited in a lawsuit filed early this year by the state of Illinois and city of Chicago against Homeland Security. It alleges Midway Blitz was designed to coerce the state and city into assisting the federal government with its deportation efforts.A federal judge has said she will decide Nov. 17 whether to let that lawsuit move forward. Related Elite Chicago police unit now investigating Border Patrol shooting of Marimar Martinez, source says Martinez crossed paths with Exum roughly one month into the Midway Blitz campaign. She said she’d been on her way to donate clothing at a church when she spotted a Chevrolet Tahoe driven by Exum that carried two additional agents.She followed the SUV, honked her horn, yelled “la migra” and tried to warn people nearby.She said she pulled her Rogue beside the Tahoe near 39th Street and Kedzie Avenue, where she said Exum swerved and their vehicles swiped each other.Body-camera footage appears to show Exum turning his steering wheel to the left, toward Martinez’s car, ahead of the collision.Martinez said she stopped her Rogue but feared being “manhandled” by the agents, so she drove away. She said she veered to her “farthest left” to avoid the agents climbing out of their vehicle on her right. As she passed, she said she saw their guns.She said she “shrugged,” scrunching her body against the steering wheel. And she heard shots fired.Martinez pulled over at a repair shop, was taken to a hospital and eventually into federal custody.Meanwhile, Exum wrote in text messages after the shooting that his superiors had been supportive of him. Then-U.S. Border Patrol Cmdr. Gregory Bovino even offered to put off Exum’s retirement following his “excellent service in Chicago,” one email shows.Another supporter told Exum in a text message, “you are a legend among agents you better f---in know that.”“Beers on me when I see you at training.” ...read more read less
